HELP!!!

Help guys!! Last night whilst playing with X white the game suddenly glitched then went blank with the following message appearing

An error has occourred. Press the eject button, remove the game disk and turn off the power to the console. Please read the wii manual for further instruction.

I have turned the console on and off numerous times, left it overnight and the game refuses to even load to the main menu now. I just keep getting the same message.

It even does the same things with other games now. I have read that this is a regular occourence to black ops users, but I cant find a solution.

The wii has been kept in pristene condition as it is not just mine, its the whole familys. I cannot afford another wii and will be really annoyed if the black ops updates have fecked my console.

Please advise.
